whats the difference among GSM, gprs, and GPRS. Im askin because I was expecting a IM via verichat.. I looked at my screen and GSM was displayed instead of the usual GPRS.. How would I be able to tell if its a network problem or device problem... I powered my 7100t on/off and removed/replaced the battery ... still the same GSM. Is there a site or number to call to check to see if there are any network outages.....
